How much power do I actually need?

For predominantly 1-6 mm sheet, 3-6 kW cuts economically with nitrogen. Thick carbon steel above 15-20 mm benefits from 12 kW and up, or oxygen cutting at lower power. Buying maximum wattage rarely pays unless thick plate or speed-critical thin sheet dominates the mix.

What should acceptance testing cover?

Cut samples across the claimed thickness range per ISO 9013 quality classes, positioning tests, pierce times, edge squareness on thick plate, and verification of consumables cost assumptions, nozzles, protective windows, and gas consumption at your typical parts.

Q: Nitrogen or oxygen assist gas?

Nitrogen produces oxide-free edges ready for welding and painting on stainless and aluminum but consumes more gas and power. Oxygen adds exothermic energy for thick carbon steel at lower laser power, leaving an oxide edge that may need cleaning.

Technical details and manufacturing context for Fiber Laser Cutting Machine

Definition

Fiber laser cutting machines focus a solid-state fiber laser, today commonly 1.5 to 30 kW and beyond, onto sheet or tube stock, melting or vaporizing a narrow kerf that assist gas ejects. They dominate sheet-metal fabrication for carbon steel, stainless, aluminum, brass, and copper, with flying-optic gantries covering formats from 3x1.5 m upward, optional shuttle tables, and tube-cutting variants with rotary chucks. Wall-plug efficiency near 30 percent, minimal maintenance versus CO2 lasers, and rapidly falling source prices made fiber the default technology.

Working Principle

The fiber source's beam travels through delivery fiber to the cutting head, where lenses focus it to a spot around 0.1 mm; capacitive height sensing keeps the nozzle standoff constant while nitrogen or oxygen assist gas blows molten material through the kerf. CNC motion executes nested profiles with piercing strategies matched to thickness.

Common Materials

welded and annealed steel frame, aluminum or steel gantry with linear motors or rack drives, fiber laser source and chiller, cutting head with protective optics, CNC controller with nesting software interface
